I personally prefer my Santos as it wears much more comfortably due to the smaller size, the Drive wears bigger than its advertised 41mm as it is a cushion shape case. I also prefer no date window for perfect symmetry. If the Drive has a medium option at 37/38mm with no date, it will be almost perfect.
With regards to the movement accuracy, my own experience is the 1904Mc in the Drive is not that accurate. It’s around +10sec a day for me. The 1847Mc on the other hand is extremely accurate at +2sec a day.
